Additional warnings
Keep the handles dry, clean and free of oil or fuel mixture.
Never touch the muffler, spark plug or other metallic parts of the engine while the engine is in operation or immediately after stopping the engine. Doing so
could result in serious burns or electrical shock.
Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off
balance.
When cutting a limb that is under tension, be alert for spring back so that you will not be struck when the tension in the wood fibres is released.
Check the tree for dead branches that could fall during the felling operation.
Always turn off the engine before setting it down .
Kickback safety precautions for chain saw users
Warning: Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip
contact in some cases may cause a lighting fast revers reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top
of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could
result in serious personal injury.
Do not rely exclusively on the safety devices built into your saw. As a chain saw user you should take several steps to keep cutting jobs free from accident or
injury.
(1) With a basic understanding of kickback you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.
(2) Keep a good grip on the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a
firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and maintain control of the saw.
(3) Make certain that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, or any other
obstruction which could be hit while you are operating the saw.
(4) Cut a high engine speeds.
(5) Do not overreach or cut above shoulder height.
(6) Follow manufacturers sharpening and maintenance instructions for saw chain.
(7) Only use replacement bar and chains specified by the manufacturer or the equivalent.
